Even when they are password protected in Word, isn't it possible for anyone to delete them (by accident I assume) and also to copy them, save as not read only, change them and put them back. Not that I think anyone would, but that is along my boss' line of concern. Ours are PDF, but we are just starting this and still keeping a paper copy. (Must have downtime for when the network is down anyway.) All the techs that are too young for bifocals prefer to look them up online.
